yellow... its really not as hard as you think. Open the Analog map and you will see that all the values are 0 right? Heres what you do. First make sure the rpm and deflection numbers are proper for your setup. Meaning i would do an rpm range of about 1000 - 6500. Then deflection from 20% - 99%. From there you look at the numbers. You want how much AFR at what throttle position and rpm. So you look at example: 75% and 2500rpms. You want 11.5 - 12.0 afr. So you put in that cell a number of 60. Why? Because for every value of 20, it will drop your AFR 1 point. So 14.7 - 3 = 11.7!!! OMG you now have an AFR of 11.7 @ 3000rpms and 75% throttle. Now i would keep that value constant all the way up to 6500 for 75% throttle. Then from there you just keep doing it for every deflection(aka throttle position or MAP, depending on which one you wired into the smt) and rpm range on the graph. Thats it, its pretty easy. All you are doing is altering the o2 signal the ECM is reading so that it adds or removes fuel. It wants to see 14.7 AT ALL TIMES during closed loop. So what you are doing is telling the ECM its seeing 17.7AFR so it ADDS fuel to get itself back to 14.7. That in turn drops your afr to 11.7 giving you the fuel you need.

Your going to run into a problem with WOT. The car does not stay in closed loop over 85% throttle i believe. dont quote me, but if thats the case, that means the analog map will not work over an 85% throttle position. BTW, if your going to use a 5th injector, i would get that SC spacer that Intense makes for allowing to put a nitrous jet after the SC, and put the 5th injector in there, so your not spraying fuel into the SC.

This is the part I'm confused on. I've never tuned a car where it jumps to open loop at wot. I'm guessing because of this you have to be extra careful of the new injectors you put in... because at wot no matter what the settings are... you're going to run at the duty cycle limit right? Or do I have that completely wrong?

Also I wouldn't reccoment the 5th injector setup on this for whatever reason. You don't want fuel going through the supercharger... but at any point after that I'd think you'd run into atomization problems. I'd be worried about fuel not spreading evenly between the cylinders. I'd almost rather put the fuel through the sc for cooling reasons.
